PULVERIZER ATTACHMENT FOR CORN PLANTERS Filed March 17,, 1928 Attorhqyynventar Patented Apr. '22, A i I UNITED-STATES CARL ROSEN, or EDIA,ILLINOIS runvnnrznn A'rr oHMEN'r 1103.003. E' V Application filed March1?,51923. Serial end of the corn'planter runner.

V Figure 2 is a side elevation thereof.

' Figure 3 is a horizontal. section therethrough taken substantially onthe line 3-3 of Figure 2.

Figure 4 is a vertical section taken substantially on the line 4 1 ofFigure 1, and

Figure 5 is a vertical section taken sub-- stantially on the line 5-5 ofFigurel.

Referring tothe-drawing in detail, it will 9 be seen that the numeral '5denotes the front upwardly curved end of a conventional corn planterrunner, which has a link 6 extending upwardly therefrom and secured tothe cross beam 7. These parts ofthe planter have been disclosed merelyfor the purpose of showing the manner in which the attachment ismounted. V

A bolt 8 holds a pair of arms9, to the lower portion of the link 6, andthese arms diverge forwardly from each other with their terminalsextended about the ends of a channel' iron beam 10 and fixed thereto asat 11.

A yoke 12 is formed on a bar 14:, which is provided with a plurality ofopenings '15. The ends of the yoke 12 are in the form of eyes 16,through which project the channel iron beam 10. A bracket 17 is fixed tothe beam 7 by a bolt 18, and has an arm 19 with g bifurcated extremitiesstraddling thebar, 14

and the bolt 20 extends through openings in the bifurcated extremitiesand through one of the openings 15.

A plurality of U-shaped clamp members I 21 are mounted on the beam 10oneadjacent. each end thereofand one at the center thereof. These U-shapedmembers have aperturedextremities through which extend the'upper portionof teeth 22, and set'screws 23 are threaded through the bights' of theclamp members 21, to engage-the bottom of the w ll be; quite japparent.

have the effect of holding moisture.

oughly eflicient for carrying out the purposes channel and the-ichanneliron beam 10 and to draw thei'teeth into binding and frictionalengagementwith the beam. f; The" adjustment afforded 15" and the boleaocontrols the'flangles at.

which the teeth will extend to as" {As shown and described, thisattachment 6 directly in frontof the planter runner may be adjusted forangle or depth as ex l jn The teeth pulverize the soil directly in frontof the runner, thereby leavingthe soil in a pulverized condition, whichwill cause it to The teeth break up clods and harrow out weedsrz Theteethbreak up crusts, leaving loose dirt to cover the corn. Also, theseteeth fill up horse tracks and loose dirt, better enabling the farmer tocover all of the corn so as to insure an evener and better. stand,because as a rule, a certain percentage of the corn which drops in thehorse tracks is not covered and does not grow or is eaten by birds andthe like. This attachment 3 enables corn to be planted shallower tham i7ordinarily, if desired, because the ground is more level in front oftherunner, whereby the planter need not be run so deep in the loose groundto insure covering ofthe corn sufficiently in small valleys or holes. Q

It will befurther seen that the structure is exceedingly simple in itsconstruction, strong and durable, easy to adjust, and thor mentioned. 7j a The present embodiment of the attachment has been disclosed inconsiderable detail, merely for the purpose of exemplification, becausein actual practice, it attains the features of advantage enumerated inthe. above deli tailed description.

It will beapparent that changes inthedetails of construction and in thecombination andarrangement of; parts may be resorted to, withoutdeparting from the spiritiand scope of the invention as hereinafterclaimed I by theo'penings v wherein the planter includes a runner, alink projecting upwardly from the forward end of the runner, and a crossbeam at the upper end of the link comprising a beam, a plurality ofteeth, means for attaching the teeth to the last mentioned beam, abracket on the first mentioned beam, ayoke. having openings in itsextremities, through which the second 7 mentioned beam extends, armsengaged with the bottom of the link and the ends of the second mentionedbeam, a bar extending from the yoke, means for adjusting the connectionof the bar with the-bracket, said means attaching the teeth and secondmentioned beam comprising U-shaped clamp members having ,aperturedextremities through which the teeth extend, and a set screw threadedthrough the bights of the U-shaped clamp membersto engage on thesecondimentioned beam to hold the teeth tightly against said secondmentioned beam. r
